Development of Tolerance-Based Performance Prediction Technology and Optimization of Actuator Design Factors of a Magnet Vertical Magnetization of AVAS

Round 1

Reviewer 1 Report

The document itself is well written and the content is interesting for me. However, there are a few things that should be improved.

Writing style:

Please avoid personal pronouns in publications.

Research content:

-You have focused on optimising tolerances in this research, which I find very interesting. However, the temperature / heating of the magnet during operation will have a much bigger impact than the tolerances (especially joule heating). Therefore, I would briefly mention that you are aware of this fact and that it is deliberately neglected in order to be able to investigate the effects of the tolerances.
- Furthermore, it would be good for the paper if the comparison or validation of the measurement results between the demonstrator and the simulation were more comparable. More specifically, I mean that in the simulation you have, correctly, focused strongly on optimising the force (20 N). In the validation, however, you compare the acceleration. The problem is that FEMM does not take into account dynamic effects such as air pressure, inertia, friction and dynamic inductance, and furthermore the force of the electromagnet will not be constant along the force-displacement curve.

You should add such a comparison of the force-displacement curves or clearly show how have taken these effects into account.

Sources:

Please add the open source software you used. I would like to explicitly refer to FEMM here, as this is a central point of your research. (This is an absolutly must!)

Figures:

The Figures should be improved, some are hard to read (e.g. Figure 16 and 21 is blurred and too small), some axis labels could be adjusted (e.g. Figure 28 frequency why not simply in kHz, Figure 25 why decimal places and not simply 0,20,40,60,80 %?)

Reviewer 2 Report

The article presents an optimization method to improve the operation of the electromagnetic force and slimming the magnetic circuit for a permanent magnet structure for magnetizing a vertical actuator for an acoustic vehicle warning system. The main part of the work is the statistical analysis of the influence of changes in selected design parameters on the operation of the electromagnetic force. However, the following issues should be addressed in the revision version:

1. The authors presented a research position that was described in very general terms. It is advisable to present (e.g. in the form of a table) the basic parameters of the measuring system components.
2. What accuracy (or measurement error) was obtained during the experimental studies?
3. Figures 16, 21 are illegible - quality should be improved.
4. Description of MT and PT markings (line 433) in the tolerance field are marked as: -.00r and -.50p. Please explain the accepted notations.
5. Will changing design parameters affect the durability and reliability of the system?
